The book is about the need for Marxists and anarchists to lay down their ideological weapons and create a single Left resistance to what capitalism is doing to the world. The hostility between the two traditions is a little like a feud between extended families handed down from generation to generation: Hatfields and McCoys in American history, or the families of Romeo and Juliet. In reality Marxism and anarchism should be like two hands, the one analyzing the structure of things, the other throwing up unending prefigurative initiatives. Neither tradition has been so successful that it can speak of the other with lofty dismissal or contempt. We need each other.
